1999 Isuzu Rodeo 3.2L DHOC Fault Code P1860 - TCC PWM Solenoid Circuit Location and Diagnosis

Model: 1999 Isuzu Rodeo Fault Code: P1860 Posted: 2009-03-03 07:30

I have a 1999 Isuzu Rodeo 2WD with a 3.2L diesel engine (DHOC) that is throwing fault code P1860. Can anyone explain what the TCC PWM Solenoid Circuit is, where exactly it's located in the vehicle, and what common issues might cause this error? I'm looking for accurate technical details to help diagnose and fix the problem. Thanks, James.
